Abstract
Le perforateur hydraulique roto-percutant comprend un corps ; un emmanchement (15) ; un piston de frappe (5) configuré pour frapper l’emmanchement (15) ; un piston de butée (13) configuré pour positionner l’emmanchement (15) dans une position d’équilibre prédéterminée, le corps et le piston de butée (13) délimitant une première chambre de commande (22) reliée de façon permanente à un conduit d’alimentation en fluide à haute pression (9) et configurée pour solliciter le piston de butée (13) vers l’avant, et une deuxième chambre de commande (25) configurée pour solliciter le piston de butée (13) vers l’avant. Le perforateur hydraulique roto-percutant (2) comprend un canal de communication fluidique (26) débouchant dans la deuxième chambre de commande (25), configuré pour alimenter la deuxième chambre de commande (25) en fluide à haute pression et pourvu d’un orifice calibré (27).
